A German teenager who discovered a macOS Keychain security flaw last month has now shared the details with Apple, after having initially refused to hand them over because of the company's lack of a bug bounty program for the Mac.
Eighteen-year-old Linus Henze dubbed the zero-day macOS vulnerability he found "KeySteal," which, as demoed in the video above, can be used to disclose all sensitive data stored in the Keychain app.
Henze said he decided to reveal the details to Apple because the bug "is very critical and because the security of macOS users is important to me."
I’ve decided to submit my keychain exploit to @Apple, even though they did not react, as it is very critical and because the security of macOS users is important to me. I’ve sent them the full details including a patch. For free of course. — Linus Henze (@LinusHenze) February 28, 2019
After Henze released the video in early February, Apple's security team reached out to him, but the researcher said he wouldn't disclose the details without a cash reward, arguing that discovering the vulnerabilities takes time.
"Even if it looks like I'm doing this just for money, this is not my motivation at all in this case," said Henze. "My motivation is to get Apple to create a bug bounty program. I think that this is the best for both Apple and Researchers."
Apple has a reward program for iOS that provides money to those who discover bugs, but there is no similar payment system for macOS bugs.

(View all)Thank you, Linus.
Now, Apple, listen to the people, and start bug bounty program.
It’s great that Apple values our privacy, but the lack of security makes all that effort pretty much useless. I think we’ve seen more critical security bugs from Apple than from any other major company.
I'm sorry but this is just BS. I used to support Windows environments for a living, what you see on Mac is literally nothing compared to what you see on Windows.
